Depressive symptoms are associated with deficits in objectively-rated detail and specificity in autobiographical future thinking for personally-relevant events. However, how depressive symptoms might affect the subjective, phenomenal characteristics of future thinking in general is not well understood. This study examined future thinking as self-reported by dysphoric (n = 79; probable major depression on the Patient Health Questionnaire and very or extremely difficult impact on functioning) and non-dysphoric adults (n = 79; as defined by normal range on the PHQ) that were matched on age and gender. The dysphoric group reported more frequent thoughts about their future in general, particularly for the long-term future, which persisted after controlling for emotional-valence. Dysphoric individuals perceived their future thinking as being more frequently vivid and detailed, more often involving mental imagery and inner speech, more often involuntary, more often unrealistic or implausible, more negatively-valenced, and more often from a third-person perspective. The findings indicate differences in the phenomenology of thinking about one's future among dysphoric individuals, some of which contrast with prior research findings. The implications for understanding autobiographical future thinking in depression are discussed, and studies are indicated to further clarify the content, function, and context of future thinking in altered affective states.
抑郁症状与对个人相关事件的自传体未来思维的客观评估的细节和特异性缺陷有关。然而,抑郁症状如何影响未来思维的主观、现象特征尚不清楚。本研究通过患者健康问卷(PHQ)评估为抑郁(n=79;有很大可能患有重度抑郁症且对功能有非常大或极大的影响)和非抑郁(n=79;PHQ 得分在正常范围内)的成年人的自我报告来考察未来思维。在控制情绪效价后,抑郁组报告的关于他们未来的想法更频繁,尤其是长期未来的想法,这一结果仍然成立。抑郁个体认为他们的未来思维更频繁、更生动、更详细,更常涉及心理意象和内在言语,更常不由自主地出现,更不现实或不可信,更消极,更常从第三人称的角度出发。这些发现表明,在抑郁个体中,对未来的思考存在现象学差异,其中一些与之前的研究结果形成对比。本文讨论了理解抑郁时自传体未来思维的意义,并指出需要进一步研究以阐明在情绪改变状态下未来思维的内容、功能和背景。
